Understanding Human Astrovirus from Pathogenesis to Treatment
<p>While human astroviruses (HAstV) were discovered nearly 45 years ago, these small positive-sense RNA viruses remain critically understudied. These studies provide fundamental new research on astrovirus pathogenesis and disruption of the gut epithelium by induction of epithelial-mesenchymal …

Understanding the Host Cellular Response to Astrovirus Infection
<p>Astrovirus is a non-enveloped positive-sense single-stranded RNA virus that infects the small intestine and causes gastrointestinal disease in most hosts. However, in immunocompromised patients, astrovirus can infect the brain, causing encephalitis and death. Here, we characterize astrovirus …

Characterizing the Cellular Response to Astrovirus Infection in the Central Nervous System
… with high morbidity and mortality rates. Astroviruses (AstVs), traditionally known for causing gastroenteritis, have recently been identified as neuroinvasive pathogens capable of inducing neurological diseases. This study explores the cellular and molecular mechanisms by which AstV, …

Characterization of human astrovirus in pediatric patients with diarrhea from rural communities of Limpopo South Africa
… caused by viruses, bacteria and parasites. Human Astrovirus (HAstVs) has been identified as a causative agent of diarrheal disease worldwide especially in young children under five years of age. Recent reports in South Africa demonstrated HAstVs as a potential pathogen associated with diarrhea. …

Identification and Characterization of Novel Astroviruses
… sporadic diarrhea specimens. One virus, Astrovirus MLB1: AstV-MLB1), was fully sequenced and determined to be a highly divergent, novel astrovirus based on phylogenetic analysis. AstV-MLB1 was further detected by RT-PCR in 4/254 fecal specimens collected at the St. Louis Children's …

Determination of the prevalence and diversity of viral gastroenteritis infections and secretor status in the elderly population of the Tshwane region in South Africa
… GI and GII, rotavirus, human adenovirus, human astrovirus and sapovirus. Careful analysis of the real-time (RT)-PCR amplification plots and export data identified 50 viruses in 40 patient specimens. Seven norovirus GI/GII dual-infections were observed and three co-infections were identified, …

Molecular characterization of economically important poultry viruses in western Canada
Avian Reovirus (ARV), Chicken Astrovirus (CAstV), and Hemorrhagic Enteritis Virus (HEV) are important enteric pathogens affecting poultry production around the world. These agents are the causative agents of Viral Arthritis (VA), White Chick Syndrome (WCS), and Hemorrhagic Enteritis (HE), …

Prevalence of human bocavirus in children with acute gastroenteritis
… (3/8; 37.5%); Norovirus (2/8; 25%) and Astrovirus (1/8; 12.5%) in this study. Conclusion: The findings highlighted the prevalence and genetic diversity of HBV strains circulating in a rural area with little or no water and sanitation infrastructure. To our knowledge this is the first …
